My “throwing water balloons at the camera” demonstration is going to have to wait a day or two, as I explain in this video, and “throwing snowballs” ain’t gonna happen any time soon… LOL.
Using Sony Vegas has taken all the work out of editing stereoscopic 3D movies, so I am moving away from the simple craft of stereography, now, and moving rapidly towards the artistic aspects, i.e. the content. It’s about time, don’t you think?
There’s no rocket science in this video, as usual. I maintain the magical 2.8% to 3.8% NetD throughout the entire clip, but since it is only one static shot, any stereoscopic kindergartener could do that.
Shot with a Sony Bloggie 3D camera. IA = .8 inch. Near point = close to 32 inches, most of the time. Far point = Infinity.
One more small thing about stereoscopic principles, here: Notice I only used a floating window on the left and right edges in this clip. That’s all you need. Cropping the top and/or bottom is no sin, though, either, so be not afraid to do that if you need to. More good news is you can slightly feather the edges, like I did here, to reduce the effects of ghosting at those edges, but you don’t have to feather the top or bottom edges, and that is true even if you crop the top and/or bottom. A straight horizontal line has no real depth cues, whatsoever. Watch my future videos for more examples. I’m just getting started. This is the easy stuff, peeps… ;/

Take A Magic Carpet Ride On A Floating Window

I’ll probably start with floating windows, because they are fun! :)
Notice in Sony Vegas in the Cookie Cutter you can use a “square” instead of a “rectangle”, thus creating a feathered floating window on _only_ the left and right edges. I will demo all of this stuff, ASAP, but you need to check this out on your 3D TV as well as on your computer monitor and on a big screen (ASAP).
The left and right vertical edges are the only edges that are stereoscopically _important_, and they are the only edges that need to be feathered to reduce ghosting at those edges. This actually means you can crop the height for any reason with the standard “crop” tool, then use a square Cookie Cutter setting for the left and right edges. Catch my drift? Bingo, baby!
You can either have top and bottom black borders or not, and that is irrelevant to stereoscopy.
I bet you were expecting me to say the opposite about this, weren’t you? Such is life in the paradoxical world of stereography!

Cinematography 3D List and “The Round Earth Society”

Yo. Peeps.
What’s going on over in the Cinematography 3D List? Anybody figuring out what the old “1/30 Stereo Base Rule” was all about?
Surely, eventually, somebody has got to figure it out… LOL.

I probably should start a stereo 3D forum called “The Round Earth Society”… where 1.2mm of 36mm is still practiced (3.3% or 1/30)… after all these years. LOL.
It’s all bout the deviation………. yup……….. always has been and and always will be.
Stereography isn’t trigonometry or rocket science. It’s just one simple formula: 1/30 (3.3%) Net Deviation.
2.5% is too flat. 4% is too deep.
3D is just an optical illusion with almost nothing in common with “reality”. The only real trick is to get everything to look perfectly round. Like the Round Earth. That is why one single number and only one number is the “key”, and that number is 1/30 (3.3%).
And the best thing is Roger Ebert won’t get those 3D headaches if you do that… LOL.

Thanks,
